Mendocino Motor - very detailed

thingiverse

UPDATE: 07. October 2018 Added: <b>22mm_solar_cell_holder.stl</b> (for solar cells with a width of 22 mm) This is a Mendocino Motor designed by me. The motor levitates and runs at an incredible speed, surpassing 2,000 rpm. I have built nearly 100 of them, and they all continue to run smoothly. Take a look at my YouTube video on how to assemble this motor (the build instructions are extremely detailed). https://youtu.be/4mt1YPeHpcE (English) https://youtu.be/aY_bkcrWcqA (German) Just for fun, here's a fully levitating Mendocino Motor: https://youtu.be/4JPtCiPu0Ns <b>The following parts are required:</b> Printed parts: 1 x mirror pad 2 x side part 1 x base magnet bracket 2 x solar cell holder 1 x coil holder Neodym magnets: 4 x side part magnet - N45-12-6 (diameter: Ø 12mm, height: 6mm) 2 x mirror pad magnet - N42-5-5-5 (edge length: 5mm) 1 x base magnet - N42-25-7 (diameter: Ø 25mm, height: 7mm) 2 x shaft magnet - N45-12/4-6 (outer diameter: Ø 12mm, inner diameter: Ø 4mm, height: 6mm) The shaft magnets and the side part magnets should be at least in N45 quality. Others: 1 x enameled copper wire Ø 0.28mm 1 x carbon fiber tube Ø 4mm 1 x chrome steel ball Ø 4mm 1 x aluminum tube Ø 12mm, length 140 mm 1 x mirror or similar round Ø 20mm 4 x seal ring 6 x solar cell (0.5V, 200mA or higher) 1 x super glue I used solar cells with a dimension of 20 x 65mm, so the solar cell holders are designed for the width of 20mm. If you need other dimensions for the solar cell holder, please leave a comment. You will need M4 headless screws in different lengths to balance the motor. Only use non-magnetic screws like stainless steel A4 and/or polyamide. Finally, take note that balancing the motor requires both static and dynamic balancing; otherwise, your Mendocino Motor will hit the ground as soon as the sun comes out.
